If the engine is still mostly stock then it's solid lifters. It definitely has some lope at idle with that slap you describe. First thing I did was put my hand over the tailpipes at idle and you can't tell any difference from one side to the other. You can't hear or tell there is a miss at idle. But start to rev it up slowly and you can hear the miss and see the engine start to shake a little like it's out of balance. I need to check the distributor just to make sure but it wasn't cheap chinese parts that went on it. Thanks for the help.
